POLE AND SHAFTS.

SPECIFICATION forming part of Letters Patent NO. 326,987, datedSeptember 29, 1885.

Application filed August 9, 1884.

To ctZZ whom it may concern.-

Be it known that I, JAMES M. JAOOBSEN, a citizen of the United States ofAmerica, residing at Preston, in the county of Jackson and State ofIowa, have invented certain new and useful improvements in means foradapting machines and vehicles to be drawn by either one or two horses,of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention relates to means for adapting a machine or vehicle to bedrawn by either one or two horses; and it consists of the constructionand combination of such means as hereinafter fully set forth and asclaimed. \Vhile my invention is applicable to any machine or vehicledesigned to be drawn by either one or two horses, it is illustrated inthis application as applied to a horse hayrake.

1n the accompanying drawings,- Figure 1 is aplan view of my improveddevices attached to a horse hay-rake. Fig. 2 is a partial plan of theunder side of the devices. Fig. 3 is a sectional view of the forwardpart of the tongue. Fig. 4 is a detail view showing a modificationofdevices for retaining the shafts in position. Fig. 5 is a perspectiveview of one of the shaft-locking devices. Fig. 6 is an end view showingthe shaft-frame attached to the rakebeam.

The main frame of the machine has the horizontal front bars, A and A,placed one above the other and connected with a rear bar, B, by thecentral pieces, 0, and side pieces, 0. The frame is coupled at a to therake-beam D, which has the teeth. I) and also the axle of thesupporting-wheels secured thereto.

E indicates the shafts, to the under sides of which,at their rearends,are halted the plates d, formed with eyes c,through which passes arod,f, which is fastened at its extremities to the lower side of theframe. The shafts extend forward between the front bars,Aand A, and maybe moved laterally along the rodf, for the purpose hereinafter setforth.

F is a tongue-point or supplementary piece which forms the foremost partof the tongue when the draft devices are adj ustedfor the at- (Nomodel.)

tachment of two horses. At the rear end of said piece is fastened aplate, 9, and a dog, h. is pivoted in a slotjust forward of plate 9,(See Fig. 8.) In adjusting the parts to form a tongue the shafts aremoved to a central position close against the frame-pieces O, as seen inFig. l. The tongue-piece F is then placed between the free ends of theshafts, which are closed against it, and a band, It, is placed on theshafts and pushed back untilitis caught by a catch, t', on the loweredge of plate g. The band It has an opening in its upper part so that itdoes not extend over the dog it but incloses both shafts, and when theband is adjusted in place it is locked by the dog,which falls intoposition, as shown in Fig. 3. A pin, m, fixed in tongue-piece F, extendsinto apertures in the shafts when the parts are brought together. Theshafts are locked in place to the frame by means of the lock-rods a,each of which is constructed to embrace a shaft and a frame-piece. andhas at its extremities the rectangular hooks 0. Each loek-rod is coupledto a shaft, and when the latter is locked to a frame-piece the lock-rodis turned down over both parts, and book 0 is closed against a shoulderor block, q, and is secured by a pivoted dog, r, as seen in Fig. 5.

\Vhen it is desired to change the draft de vices from a tongue to shaftsfor a single horse, the dog h is lifted and the band It and tongue Fremoved. The dogs rare then raised and the lock-rodsn are turned up. Theshafts may then be moved away from frame-pieces C and closed againstside pieces, 0, when they may be locked thereto by means of the lockrodsand the dogs 1' on the side pieces. In Fig. 1 the shafts are indicatedin dotted lines locked to the side pieces of the frame.

The shafts may be retained in position by means of straps o, inclosingfront bar, A, as shown in Fig. 4, and with such construction the bar Amay be dispensed with.

A indicates a whiffletree, which answers the purpose of a doubletreewhen two horses are attached.

Having described my invention, I claim as new and desire to secure byLetters Patent 1. The combination,with a frame eonstructed to carrylaterally -adjustable poles and shafts, and provided with the end andcentral pieces, 0 G, as herein set forth, of the rod f, attached to theframe, the shaft E, provided with the plates d having eyes a,constructed to receive and slide loosely on the rod, and the lock-rodsn, attached to the shafts and adapted to lock them in position to the:pieces 0 O, substantially as and for the purposes described.

2. The combination, with the laterally-adjustable shafts E, of theremovable tongue piece F, the pivoted dog h, the catch 11, and the bandis, substantially as and for the purposes described.
